-- First head-to-head trial showing greater safety and efficacy of IMBRUVICA-based therapy versus FCR
-- Results from this interim analysis featured as a Late-Breaker at ASH 2018 (abstract #LBA-4)
SAN DIEGO, Dec. 4, 2018 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson announced today results from the National Cancer Institute (NCI)-sponsored Phase 3 study (E1912) led by the ECOG-ACRIN Research Group (ECOG-ACRIN) evaluating IMBRUVICA® (ibrutinib) plus rituximab compared to a chemotherapy regimen of fludarabine, cyclophosphamide, and rituximab (FCR) in previously untreated patients aged 70 years or younger with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).1 With nearly three years of follow-up, the data showed IMBRUVICA plus rituximab significantly prolonged progression-free survival (PFS) and overall survival (OS) versus FCR.
The findings were presented during the Late-Breaker abstract oral session at the 60th American Society of Hematology (ASH) Annual Meeting (abstract #LBA-4). IMBRUVICA, a Bruton’s tyrosine kinase (BTK) inhibitor studied in patients with CLL for up to seven years, is jointly developed and commercialized by Janssen Biotech, Inc., and Pharmacyclics LLC, an AbbVie company.2 The federally funded study was designed by researchers with ECOG-ACRIN. It was conducted through the NCI’s National Clinical Trials Network. Pharmacyclics LLC provided ibrutinib under a cooperative research and development agreement with NCI and a separate agreement with ECOG-ACRIN.
“While FCR has long been the most commonly used treatment regimen for younger patients with chronic lymphocytic leukemia, we have been eagerly awaiting a treatment with an improved safety and efficacy profile for these patients,” said Craig Tendler, M.D., Vice President, Clinical Development and Global Medical Affairs, Janssen Research & Development, LLC. “The results from this Phase 3 head-to-head trial demonstrate the significant treatment benefit of the IMBRUVICA combination versus FCR.”
At a median follow-up of 33.4 months, IMBRUVICA plus rituximab showed significantly prolonged PFS compared to FCR in previously untreated patients aged 70 years or younger with CLL/SLL (HR: 0.35; 95 percent confidence interval [CI]: 0.22-0.56; p<0.0001). The study also demonstrated an improved OS for the IMBRUVICA plus rituximab treatment arm versus FCR (HR: 0.17; 95 percent CI: 0.05-0.54; p=0.0003). In a subgroup analysis for PFS, IMBRUVICA plus rituximab showed prolonged PFS independent of age, sex, performance status (0-2), disease stage, or the presence/absence of deletion 11q23.
About the Data Presentation
Abstract #LBA-4: A Randomized Phase III Study of Ibrutinib (PCI-32765)-Based Therapy Vs. Standard Fludarabine, Cyclophosphamide, and Rituximab (FCR) Chemoimmunotherapy in Untreated Younger Patients with Chronic Lymphocytic Leukemia (CLL): A Trial of the ECOG-ACRIN Cancer Research Group (E1912)
Late-Breaker Oral Presentation: Tuesday, December 4 at 7:30am PT
The Phase 3 study (E1912) evaluated previously untreated patients with CLL or SLL aged 70 years or younger who were randomly assigned to receive IMBRUVICA (420 mg/day until disease progression) and rituximab (50 mg/m2 on day 1 of cycle 2; 325 mg/m2 on day 2 of cycle 2; 500 mg/m2 on day 1 of cycles 3-7) (n=354) or six courses of intravenous fludarabine (25 mg/m2) and cyclophosphamide (250 mg/m2) days 1-3 with rituximab (50 mg/m2 on day 1 of cycle 1; 325 mg/m2 on day 2 of cycle 1; 500 mg/m2 on day 1 of cycles 2-6) every 28-days (n=175). The primary endpoint was PFS with a secondary endpoint of OS.
With a median follow-up of 33.4 months, the interim analysis observed 77 PFS events and 14 deaths. IMBRUVICA plus rituximab significantly improved PFS compared to FCR (HR: 0.35; 95 percent CI: 0.22-0.56; p<0.0001); the pre-specified boundary for PFS was crossed. The IMBRUVICA plus rituximab treatment arm also showed improved OS (HR: 0.17; 95 percent CI: 0.05-0.54; p=0.0003, pre-specified boundary for superiority p=0.0005).
In a subgroup analysis for PFS, IMBRUVICA plus rituximab showed prolonged PFS independent of age, sex, performance status (0-2), disease stage, or the presence/absence of cytogenetic abnormality, deletion 11q23. With current follow-up, IMBRUVICA plus rituximab was also superior to FCR for IGHV unmutated patients (HR: 0.26; 95 percent CI: 0.14-0.50; p<0.0001) but not IGHV mutated patients (HR: 0.44; 95 percent CI: 0.14-0.135; p=0.07).
Grade 3/4 treatment-related adverse events were observed in 58 percent of IMBRUVICA plus rituximab treated patients and 72 percent of FCR treated patients (p=0.0042). FCR was more frequently associated with Grade 3 and 4 neutropenia (FCR: 44 percent vs. IMBRUVICA plus rituximab: 23 percent; p<0·0001) and infectious complications (FCR: 18 percent vs. IMBRUVICA plus rituximab: 7 percent; p<0.0001).
About IMBRUVICA
IMBRUVICA (ibrutinib) is a first-in-class, once-daily oral medicine that works differently than chemotherapy as it blocks the Bruton’s tyrosine kinase (BTK) protein. The BTK protein sends important signals that tell B cells to mature and produce antibodies; BTK signaling is needed by specific cancer cells to multiply and spread.3,4 By blocking BTK, IMBRUVICA may help move abnormal B cells out of their nourishing environments in the lymph nodes, bone marrow, and other organs.5,6
IMBRUVICA is approved in more than 90 countries, and, to date, has been used to treat more than 135,000 patients worldwide across approved indications. It was first approved by the U.S. Food and Drug Administration in 2013, and today is indicated in six disease areas, including five hematologic cancers – chronic lymphocytic leukemia (CLL) with or without 17p deletion (del17p), small lymphocytic lymphoma (SLL) with or without del17p, Waldenström’s macroglobulinemia (WM), previously-treated patients with mantle cell lymphoma (MCL)*, previously-treated patients with marginal zone lymphoma (MZL) who require systemic therapy and have received at least one prior anti-CD20-based therapy* – and previously-treated patients with chronic graft-versus-host disease (cGVHD) after failure of one or more lines of systemic therapy.6
IMBRUVICA is the first and only FDA-approved medicine in WM, MZL* and cGVHD. IMBRUVICA has been granted four Breakthrough Therapy Designations by the FDA, and it was one of the first medicines to receive U.S. approval through the Breakthrough Therapy Designation.
IMBRUVICA is a comprehensively studied molecule in the oncology industry. The robust clinical oncology development program includes more than 150 active clinical trials studying IMBRUVICA alone and in combination with other medicines in several blood cancers and other serious diseases.

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage: Fatal bleeding events have occurred in patients treated with IMBRUVICA®. Grade 3 or higher bleeding events (intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post-procedural hemorrhage) have occurred in 3% of patients, with fatalities occurring in 0.3% of 1,011 patients exposed to IMBRUVICA® in clinical trials. Bleeding events of any grade, including bruising and petechiae, occurred in 44% of patients treated with IMBRUVICA®.
The mechanism for the bleeding events is not well understood.
IMBRUVICA® may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies and patients should be monitored for signs of bleeding.
Consider the benefit-risk of withholding IMBRUVICA® for at least 3 to 7 days pre and post-surgery depending upon the type of surgery and the risk of bleeding.
Infections: Fatal and non-fatal infections (including bacterial, viral, or fungal) have occurred with IMBRUVICA® therapy. Grade 3 or greater infections occurred in 24% of 1,011 patients exposed to IMBRUVICA® in clinical trials. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with IMBRUVICA®. Consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections.
Monitor and evaluate patients for fever and infections and treat appropriately.
Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (23%), thrombocytopenia (8%), and anemia (3%) based on laboratory measurements occurred in patients with B-cell malignancies treated with single agent IMBRUVICA®.
Monitor complete blood counts monthly.
Cardiac Arrhythmias: Fatal and serious cardiac arrhythmias have occurred with IMBRUVICA® therapy. Grade 3 or greater ventricular tachyarrhythmias occurred in 0.2% of patients, and Grade 3 or greater atrial fibrillation and atrial flutter occurred in 4% of 1,011 patients exposed to IMBRUVICA® in clinical trials. These events have occurred particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of cardiac arrhythmias.
Periodically monitor patients clinically for cardiac arrhythmias. Obtain an ECG for patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness, syncope, chest pain) or new onset dyspnea. Manage cardiac arrhythmias appropriately, and if it persists, consider the risks and benefits of IMBRUVICA® treatment and follow dose modification guidelines.
Hypertension: Hypertension has occurred in 12% of 1,011 patients treated with IMBRUVICA® in clinical trials with a median time to onset of 5 months (range, 0.03 to 22 months). Monitor patients for new onset hypertension or hypertension that is not adequately controlled after starting IMBRUVICA®. Adjust existing anti-hypertensive medications and/or initiate anti-hypertensive treatment as appropriate.
Second Primary Malignancies: Other malignancies (9%) including non-skin carcinomas (2%) have occurred in 1,011 patients treated with IMBRUVICA® in clinical trials. The most frequent second primary malignancy was non-melanoma skin cancer (6%).
Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with IMBRUVICA® therapy. Assess the baseline risk (e.g., high tumor burden) and take appropriate precautions.
Monitor patients closely and treat as appropriate.
Embryo-Fetal Toxicity: Based on findings in animals, IMBRUVICA® can cause fetal harm when administered to a pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICA® and for 1 month after cessation of therapy. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Advise men to avoid fathering a child during the same time period.
